BUCKLE.

SPECIFICATION forming part of Letters Patent No. 368,299, dated August16, 1887,

Application liled January 28, 1887. Serial No. 225,827.

To all whom it may concern.-

Be it known that I, THOMAS MiToHELL, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New 5 York,have invented certain new and useful Improvements in Buckles; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to an improvement in 5 buckles for leather,cloth, or flexible straps, and is so constructed that the strap is heldexactl y at that point of strain desired firmly and positive and it furtherconsists in certain peculiarities of construction and combinationof parts, securing such strength, ease of action, and without the leastslack in shutting the buckle, as will be hereinafter set forth.

In the annexed drawings, illustrating my invention, Figure 1 is a sideView of the buckle 5 closed upon astrap, with one ofthe side framesremoved to show the interior construction. Fig. 2 is likewise a side oredge view of the buckle open, showing the handle-tube provided with atongue standing perpendicularly. Fig. 3 is a top view showing the sidesof the frame, the tubes and pins or pin bearings within them, and whichform the shoulders against which the pins are riveted at each end,forming the frame of the buckle. Fig. 4 is an 5 edge view of thehandle-tube provided with a tongue.

Like letters of reference denote like parts in the several figures.

a represents the side of the framepieccs, as

0 shown in Figs. 1 and 2.

1) represents the hollow of the tube for the pin-bearer in Fig. 1 andthe projectingriveted end in Fig. 3.

0 represents the hollow in the handle-tube,

5 provided with the tongue, as shown in Fig. 1,

and the projecting pin-bearer, upon which it v (No model.)

plays, in Fig. 3. This tongue may be formed of one or more lips, eachlonger than the preceding one,in order to hold equally firm thicker orthinner straps, or the variations of thickness in the same strap.

d represents the hollow of the tube around which the strap-holder isformed and plays, as shown in Fig. 1, and its projecting pin-bearer inFig. 3.

0 represents the handle, and g the tongue, of the handle-tubular tongue,as shown in Fig. 1 and in section, Fig. 4.

h represents the strap-holder,and k the rivetfasteniug, as shown in Fig.3; also, Z is the point at which the tongue presses the strap against itin Fig. 1. Its place is also shown in Fig. 3. i represents the wholestrap in Fig. 1 and its sections in Fig. 2, and its cut-away section inFig. 3.

e of Fig. l is the handle for closing and opening the buckle, and 9represents the tongue of the handle-tube tongue.

a n n represent the plain tubes without their appendages.

1t will. be understood that I do not herein limit myself to the exactarrangement of the parts just described, but reserve to myself theliberty of departing and varying therefrom, as shall be deemed bestsuited to the easy construction and effective operation ofthe buckle,without, however, departing from the essential features of my invention,as herein described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The handle-tube provided with a tongue, in combination with the piercedside frame piece or pieces in which the pins play or rest, and theoutside bearers, a a, when constructed and operated substantially as andfor the purpose set forth.
